A.B. "Buzzy" Krongrad, the brother of State Dept. Inspector General Howard Krongrad who is under investigation for lying to Congress, resigned from his seat on an advisory board for Blackwater on Friday:

[Krongard's resignation comes] two days after the relationship with the security contractor was sharply criticized by a congressional oversight committee.

Erik Prince, Blackwater's top executive, said the conflict of interest questions raised by the connection prompted ... Krongard to submit his resignation.

"I have reluctantly accepted it," Prince said in a statement.

On Friday, Henry Waxman, chairman of the House Committee on Oversight and Government Reform, announced that is committee will look into Howard Krongard's testimony last week in which denied that Buzzy had a relationship with Blackwater, only to recant that testimony when confronted with the facts. After the hearings, Buzzy Krongrad told reporters and then committee staff that, contrary to Howard's testimony, Buzzy had recently informed him that he was joining the Blackwater advisory board.

Both Krongard brothers --- who are said not to get along --- are expected to be called to testify in hearings that will examine the perjury claim against Howard Krongard.
